Question: What causes plate tectonics, in other words what causes the plates to move? What causes plate tectonics, in other words what causes the plates to move?

Answer: Earth’s center, or core, is very hot, about 9000 degrees F. This heat causes molten rock deep within the mantle layer to move. Warm material rises, cools, and eventually sinks down. As the cool material sinks towards the Earth’s core it is warmed and rises to the top again. This type of movement is called a convection cell. We used to assume that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that the plates themselves play an important role in the convection process. How can plates play an active part in the convention process instead of just surfing along? Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink. New parts of a plate rise because they are warm and thin. As hot magma rises to the surface at spreading ridges and forms new crust, the new crust may actively push the rest of a plate out of its way. This is called ridge push. Old parts of a plate are likely to sink down into the mantle at subduction zones because they are colder, thicker and denser than the warm mantle material underneath them. This is called slab pull.

Question: What are the main causes of divorce? I know there are many reasons as to why people get divorced, but what are? the main reasons, situations, causes, that cause a wife and husband to break-up. Is it financial problems? Communication? I know cheating or having an affair is obvious, but I don't think that happens as often for other reasons, what usually causes a wife and husband, even if they have children or not, what usually causes them to fight and argue that will ultimately end in divorce or separation? I am just wondering because the divorce rate is very high, like at least 50 percent of marriages end in divorce, what are the main causes of divorce?

Answer: it begins with being unable to communicate, or problem solve, but betrayal is the real reason it ends.

Question: What causes the chemical imbalances that lead to depression? The medical fraternity often claims that a major cause of depression is chemical imbalance. However, there is seldom any discussion about what causes the chemical imbalance. I would like to learn what this may be. I have my own thoughts but would like to hear from others about probable causes.

Answer: You posted an answer to my question regarding my thesis and I'd just like to say I definitely agree that depression is being blamed "brain abnormalities", such as serotonin reputake. However, at this point, we don't even fully understand the full spectrum of how these chemicals work and what exactly they do. The scary part then is why are all of these medications being prescribed when we don't even understand what's wrong? And the even scarier part is they don't even know what anti-depressants really do to the brain!! The little that pharmaceutical companies do know is being hidden from the FDA and the general public. Check out some of Peter Breggin's books, he makes a lot of interesting arguments against simply treating psychological disorders with antidepressants. Depression, anxiety, etc. is far more complicated than simply a brain abnormality. It's a build up of past experiences and stressors and how we think about and interpret them.

Question: What causes a vagina to be tight or loose? What activities cause it to get loose? I've heard a lot of sex, being overweight, and childbirth cause the vagina to become looser. But then again I've heard that all of the aforementioned things are myths and the vagina doesn't get looser because of those activities. So what causes a loose vagina, and how do you tighten it?

Answer: It's almost entirely genetic and hormonal; when you're aroused, your vagina tends to loosen somewhat. Childbirth only temporarily loosens the vaginal walls; ,many women find that upon beginning to have sex again (usually about one month after childbirth) that they are almost painfully tight. Being overweight can actually make your vagina "fatter"-- more fat deposits in the vaginal walls, which will make it feel smaller. Sex usually has no impact on vaginal tightness, except (over time) at the opening. Kegel exercises (when you flex the same muscle you use to stop urinating) and vaginal barbells or weights are widely recommended to increase tightness, but this only applies to the vaginal opening, not to the walls.

Question: What are causes for people to communicate via text messaging rather than phone itself? I am writing an English paper about cause and effect. My topic is going to be on why more people rely on communicating through text messaging. I need to find out the causes of those. We are also required to come up with interview questions to ask ppl and I need some help with those too. Does anyone have any questions or causes so I can write my paper?

Answer: Easy. Because making a ohone call takes longer because you have to say so much more than one sentence. You have to have a greeting and an ending and most of the time you end up talking about stuff unrelated to the point. That's okay when you have time to chit-chat, but texting is straight, fast, and to the point. I personally feel like its really wierd how no one talks on the phone anymore..this whole technical generation is scary. No one talks on the phone anymore because we can text, email, instant message. HELL People would rather send a FAX then make a phone call.

Question: What causes nasal cavity cancerr and what should i do do minimize the chance of having it? What causes nasal cavity cancerr and what should i do do minimize the chance of having it? What causes nasal cavity cancerr and what should i do do minimize the chance of having it? How do i know if i have it?

Answer: Smoking can be a huge factor, since you're inhaling. Other causes could be unhealthy working living environments where you may breathe in carcinogens. Snorting drugs like cocaine could cause it too, since you're wearing down the protective tissues in your nasal cavity. If you think you have it, see your doctor, they can do a CAT scan or MRI

Question: What causes whites to become grey and dingy over time? What is it that causes white clothes and towels to get that grey dingy look over time? I bought some white towels a year ago and they already look so dingy. A) What causes this? (besides washing them with other colors, because I have never done this and they are still dingy looking) B) How can I make my stuff white again?

Answer: The dingy look comes from redeposited soils, hard water, poorly rinsed clothes, tumble drying. A lot of these contribute to this. To keep your towels looking bright, I suggest that you wash them once in a while in "all color bleach". You will need to add this to the detergent and then stop the machine in the wash cycle and let the towels soak for about 8-10 hours. Then just restart the cycle and let it finish. Doing this in addition to avoiding the above problems will keep them looking nicer longer.

Question: What causes a penny to slide on a turn table? If a penny is stationary on a turntable due to static friction, and the turntable turns faster and faster. What eventually causes the penny to slide outward from the radius? I don't think theres a force that causes it because physics teachers say there is no force that forces it away from the center.

Answer: It depends on the frame of reference - how you look at it. The rotation of the turntable exerts a force in two perpendicular components - a centripetal component, which pull the coin towards the centre, and a rotational component, which pushes it outward. The centripetal component in this case is effectively all friction. Once the turntable is moving fast enough, this will defeat the friction, and with nothing to hold it down the coin moves outwards. It's not that there's a force pushing it outwards, but rather that there is no longer a force pulling it inwards.

Question: What causes my daughter to have big poop and causing her pain when she has to go? My 15 month old daughter have hard stool all the time. It's pebbles like ever sinced she switched to whole milk. Anways there are times that she has big logs that I have to help her get it out. What causes this? I am feeding her lots of fruits and vegetables.

Answer: Fruit and vegetables are very healthy foods for the daily diet, but in moderation.Fruit and vegetables provide us with vitamins and fibre and other health benefits. If you have too much fibre you can actually become clogged/constipated. I would suggest that your daughter has no more than 2 - 3 pieces of fruit a day and only 2 cups of cooked mixed vegetables a day. Try and limit how much fruit juice you give her also, just think about how many pieces of fruit are required to make the juice for one cup of drink......heaps. Try and get your daughter to drink at least three cups of water a day. Drinking water is an excellent way to help soften her poos and make it easier to be eliminated from her body.

Question: What causes the warming reaction in warming cosmetics? What causes the warming reaction in "warming" products when they are introduced into water. I see a high concentration of citric acid, which seems a bit much if just used as a preservative or mild exfoliant. So which cosmetic ingrediants cause this reaction and why?

Answer: Sensitizer Taraxcum officinale extract: It increases solubility of fragrance oils into water. Marjoram oil: Increases blood flow used in lotions, hair products and makeup. When you have an increase in blood flow you begin to feel a warming sensation and sometimes gives you rosey cheeks or blotching to the skin.

Question: What causes some people to create papparazzi and have constant crowds following them and bodyguards always? always around them while other people don't have that? For instance, what caused Michael Jackson to create constant crowds around him, always had bodyguards while his brothers when they go out they don't need bodyguards nor do cameras follow them? Or what causes Paris Hilton and Britney Spears to create papparazzi while other hollywood figures don't create that? What accounts for the differentiation between these figures?

Answer: Some, like Jackson, just have broad appeal and fan bases who turn out to see them no matter where they go. The paparazzi will follow the crowds or try to be there first. Others like Paris Hilton try to attract attention, to the point of informing paparazzi where they'll be for a photo op because that is their sole popularity/talent. Others like Britney, Lindsey Lohan and lately Tiger Woods create the craziness by their own actions, mistakes, bad decisions, and sometimes on purpose. Constant attention from the paparazzi is more a curse than a blessing. Other celebrities have a more low key approach and manage to live their lives and stay out of the news until they want something in print.

Question: What causes some people to dream in black and white, and others to dream in color? I rarely ever dream in color, and I was just wondering what causes us to dream in black and white. A lot of my friends say they dream in color, and I feel like me and my other friend are the only ones who dream in black and white. What causes our dreams to be in a certain color?

Answer: Hello, I have found a very interesting article, it may answer your question: It's quite a commonly-held belief that we dream in BLACK and WHITE! It's not true, of course. You can see this by the fact that at least every now-and-then you can remember a dream in which there was some colour. So why is it believed that we dream in black and white? I know why, and I'll try to explain it, but it's not an easy thing to explain as there are extra concepts required. The first thing is that YES it's true there are dreams in which there is no colour, but that is not because they're in black and white! What happens is that in dreaming, the automatic checking systems that go on in the mind are turned off. So, if the queen of England visited and brought a few aliens round for tea you'd probably be working out if you'd got enough cups and whether the biscuits you'd got would be acceptable, rather than thinking that it was a bit odd to be visited by the queen and some aliens. Also, in dreams, things which aren't relevant are just UNSPECIFIED, and there are no alarm bells to flag up that something is MISSING. So, when you're flying on a magic carpet, you can't necessarily say which shoes you might have been wearing. But not being able to tell what shoes you had on does not imply you were barefoot. This is what happens with the COLOUR situation. In a dream, where the colour of something is relevant, you see colour, but where the colour is not relevant, there is NO COLOUR INFORMATION. But that doesn't mean it's in black&white. Black and white is a function of televisions when the colour information is removed, but the same is not true of the mind. Take a look at a few examples, grass for example might not be green in a dream, but it's not grey like in a black and white movie. It's just not relevant what colour it is. Most people's hair colour is not grey in a dream, but just "average coloured". If you saw Zyra in a dream, you'd probably see a vivid hair colour but not necessarily be able to tell what colour it was! It is this, the fact that "missing" information is not noticed to be missing, that fools the conscious mind on waking up into concluding that therefore by implication the dream must have been in black and white, whereas in fact it was just that colour wasn't important in that particular dream. Plus, if anyone actually still believes that in dreams there is never any colour because the experts always say "we dream in black and white", just stop believing the experts! You'll soon wake up and find you have dreamt something which had some vivid colour!

Question: What causes black women to have a deep voice and facial hair like males do? What things causes black women to sound like men when they talk and what causes them to grow facial hair and have to shave like men do?

Answer: Black people are very different from White people. People think that it's only the skin but the skin is just the most obvious difference that you see immediately. It's evolution - black people appear to be more like animals. Whites on the other hand were forced to evolve more mentally and lost some of their animal looks. Also if you notice blacks like shiny things like animals. A white person would find golden teeth ugly but to them it's the epitome of beauty. I was in a Black school /international/ and black girls were very fat, and had muscles and were pretty much very manly and ugly. They also had very distinctive smell (sweat). Also their hair was like a boys's hair -short and there noses just made it worse.

Question: What causes skin cancer and what are the effects? Well, I am 13, and I have gotten two severe sunburns this past month. My mom said they were pretty bad, and they can cause skin cancer in the future. Is this really true? If not what are the real causes of skin cancer? What are the effects?

Answer: Skin Cancer Causes Ultraviolet (UV) light exposure, most commonly from sunlight, is overwhelmingly the most frequent cause of skin cancer. Other important causes of skin cancer include the following: * Use of tanning booths * Immunosuppression—impairment of the immune system, which protects the body from foreign entities, such as germs or substances that cause an allergic reaction. This may occur as a consequence of some diseases or can be due to medications prescribed to combat autoimmune diseases or prevent organ transplant rejection. * Exposure to unusually high levels of x-rays * Contact with certain chemicals—arsenic (miners, sheep shearers, and farmers), hydrocarbons in tar, oils, and soot (may cause squamous cell carcinoma) Regarding your mother's comment, people who had at least one severe sunburn early in life have a greater risk of developing skin cancer. Mom is right! Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy.

Question: What causes my finger to turn momentarily white and numb? My pointer finger pad/ nail will turn white, and a little numb for a while and random times, and then after a while it will return back to normal. I don't know under what circumstance it will cause this, or when it would turn back to normal. Does anyone know what causes this, or anything to be concerned with?

Answer: These symptoms could occur if you are doing something like holding a pencil too tight (an example only). The only way to know for sure is to see your doctor for further evaluation of the situation.

Question: What causes masturbation and sexual addictions in a guy? Masturbation and sexual addictions are such addictions which are said to be more powerful than drug and cigarette addictions. But what causes masturbation and sexual addictions to be so powerful? I've heard almost every person addicted with masturbation and sexual addictions. What really causes masturbation and sexual addictions in guys? Scientific and medical points will be highly appreciated. Thanks.

Answer: I am a bit confused by your linking masturbation, the body's natural and healthy response to unrelieved sexual tensions to sexual addictions. Neither do I understand your labeling of the normal male desire to have sex with another being as an addiction. A man is driven by hormones and is only fulfilling his natural sexual role.
